Abstract

In a method of continuously producing rectangular foam blocks wherein a foamable polyurethane-reaction mixture is deposited on a bottom web moved by a conveyor belt, the surface of the rising foam is covered by a cover web which is withdrawn from the foam surface by a deviating device disposed near a location at which the foaming of the mixture is terminated, and the cover web is further advanced by means of a deviating roller, a method of synchronizing the movements of the cover web and the bottom web includes driving the deviating roller, through a transmission coupled to the conveyor belt, at a peripheral speed that is synchronized with the conveyor speed of the conveyor belt, and passing the cover web between the deviating roller and a roller adjustable in elevation and in pressure contact with the deviating roller.
